Hi @Moyan,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing a blank screen with a flashing Caps Lock light on an HP Laptop typically indicates a hardware issue. Here's a step-by-step guide to troubleshoot:

Check for Beep Codes:

• When the laptop starts up, listen for any beep codes. These can help diagnose the problem. Refer to HP’s documentation or website for the beep code meanings.

Perform a Hard Reset:

• Turn off the laptop.
• Disconnect all external devices (USB drives, printers, etc.).
• Remove the battery (if it’s removable) and unplug the AC adapter.
• Press and hold the power button for about 15-20 seconds to discharge any residual power.
• Reinsert the battery (if removed), plug in the AC adapter, and try turning on the laptop again.

Check RAM:

• Power off the laptop and remove the battery (if removable).
• Open the RAM compartment (refer to the laptop’s manual for instructions).
• Reseat the RAM: Remove the RAM sticks and reinsert them to ensure they are properly seated.
• Try booting up the laptop again.

Check for External Display:

• Connect the laptop to an external monitor or TV using the appropriate cable.
• Switch the display mode using the Fn + F4 (or similar) key combination to see if the display appears on the external monitor.

Inspect for Loose Connections:

• If comfortable doing so, open the laptop’s back panel and check for any loose or disconnected cables.

Try BIOS Recovery:

• Turn off the laptop.
• Hold down the Windows key and B key (or V key on some models), then press and hold the power button for 8-10 seconds, then release the keys.
• The laptop should attempt to start BIOS recovery if this method is supported.
